Superior Cobalt Steel Alloy From Osprey®
Osprey® 18Ni300 is a maraging steel, a class of ultra-high strength, high hardness and high toughness steels that can be welded without preheating either in annealed (easy to machine) or heat-treated condition.
These properties make Osprey® 18Ni300 ideal for the laser powder bed fusion (L-PBF) process to manufacture parts with complex geometries for demanding applications that require an excellent combination of strength, toughness, and thermal stability.

Frequently Asked Questions
What is 18Ni300?
This is an alloy of 18% nickel and 300-grade maraging steel which is a popular metal used in the aerospace industry owing to its exceptional strength, durability, and resistance to corrosion. This metal powder has been designed for high-performance applications of demanding components.
What are the mechanical properties of 18Ni300?
18Ni300 from Osprey® is manufactured through Vacuum Inert Gas Atomized (VIGA) and Inert Gas Atomized (IGA) powder which results in tensile strength and yield strength of over 2,000 MPa and fatigue strength of approximately 700 MPa.
What are the uses of cobalt steel alloy?
Alloys of cobalt and steel are remarkably tough and resistant to wear, making them an ideal choice for conformal-cooled mold tooling and rubber-tyre mold (sipes) applications. A high heat resistance makes them suitable for machining aerospace components as well.
